The introduction of a competency approach and the emphasis on learning outcomes change the approach of the current planning and programming of the educational process. To increase the efficiency of teaching and learning, emphasis should be placed on the role and competence of teachers in teaching and organizing studentfocused activities and on the quality of planning the educational process. The purpose of this graduation thesis was to explore the opinions of teachers involved in the implementation of the experimental program "Škola za život" aimed at the development of competences and the modern teaching method. The analysis of the evaluation sheets shows the opinions of all elementary school teachers (N = 23) involved in the implementation of the experimental program in the context of: realization of learning outcomes (the achievement of teaching activities and methods) with expressed difficulties, changes in teacher work (planning and implementation of the process), application of formative evaluation and digital teaching tools, as well as reviewing the implementation of the experimental program itself. First class teachers were further interviewed about the contemporary teaching, the particularities of teaching and learning planning in the presented organizational teaching processes according to contemporary methods of curricular reform. The results indicate that teachers recognize the potential of a contemporary competence approach and student-centered learning and teaching, but at the same time they are aware of the difficulties of implementing the experimental program that only partially achieve their core goals in practice.
